When I try to bring up the MS-DOS prompt it sometimes works and sometimes doesn't. When it doesn't, an error message appears (can't reproduce it exactly now because of course the thing is working perfectly!) but something to the effect "This program has performed an illegal operation and will be shut down..." When I go to details it says something about an error in SYMEVENT or something. There doesn't seem to be any pattern to whether it works or not. Even if I restart the computer, that is not necessarily a guarantee that it will work straight off the bat.
When I choose Start - Run - Command, this works fine. The computer also restarts in DOS mode with no problem.
In the shortcut to the MS-DOS prompt, the option in programs is Suggest MS-DOS mode as necessary.
Any help appreciated.
